In some countries, like Canada and Japan, the iPhone X costs about $100 more than it does in the U.S. In other nations, like Italy and Ireland, the phone is over $400 more expensive than it is in the States.

Apple analyst Gene Munster of Loup Ventures said that iPhones tend to cost between $50 and $300 more internationally.

But higher prices won't necessarily deter global shoppers from buying a new iPhone. "It usually isn't a deal-breaker," he said. He thinks that will be especially true with the futuristic iPhoneX, which looks so different from other models.

Frank Gillett, an analyst at Forrester Research, pointed out that it's hard to compare prices across countries not only because they include currency conversions and local taxes, but because the device's true cost also depends on the average resident's income.

With that in mind, here's how much the iPhone X costs in 15 countries, according to Apple's website. The prices were converted to U.S. dollars using Google's currency calculator.
